Yesterday, our pair behaved quite bizarrrely for several hours. Diamond would not settle on the eggs and often left the nest box completely and every time Bula tried to incubate, she would arrive back and chase him out, sometimes quite vigorously. I noticed that she was often looking up as if there might have been another bird of prey in the sky, but of course I can’t be sure, and by the time I observed this, all had returned to normal, so there was no point in going outside to check. This went on for several hours until she finally let Bula settle for a while and eventually resumed her own incubation later in the afternoon. I was a bit worried as it is very unseasonably cold here today, and wet and I didn’t like to see the eggs left that long.
